Brieffold
The brief
Design agencies waste hours per week writing intake briefs. I wanted a tool that takes 5 questions and outputs a 2-page brief good enough to send to a client.
The build
- Mon
Kickoff. Defined the 5-question funnel and the brief template.
- Tue
Auth, schema (orgs, briefs, generations), Claude API wired with streaming.
- Wed
Generation UI, brief editor, share-link export.
- Thu
Stripe metered billing, customer portal, abuse rate limit.
- Fri
Deploy on brieffold.com, custom email, repo handover.
Stack
- · Next.js 16 + Tailwind v4
- · Cloudflare Pages + Workers + R2
- · Anthropic Claude (Sonnet) for generation
- · Postgres D1 + Drizzle
- · Better-Auth with magic links
- · Stripe metered billing on 'briefs generated'
- · Sentry + PostHog
Outcome
First $2K MRR in 17 days. Featured on Product Hunt week 4. Now 220 paying agencies on the $49/mo plan.
I'd been wireframing for two months. The version they shipped on Friday converted better than mine, and they did it in a week.
